UNITED STATES PATENT yJOHN J. DwYEE, or NEW YORK, n. Y.

SASH-FOLLOWER.

SPECIFICATION' forming part of Letters Patent No. 283,384, Adated August21, 1883.

f Application tiled June S, 1883. (No model.)

To all whom, it may concern:

Be it known that I, J OHN J. DwYnR, of New York, in the county of NewYork and State of New York, have invented anew and useful Improvement inSash-Followers; and I do declare that the following. is a full, clear,and exact description thereof, which will enable others skilled in theart to make and use the same, reference being had to the accompanyingdrawings, forming part of this speciflcation.

This invention relates to an improvement in sash-followcrs,which arecontrivances for clos:

jing the opening in the head-piece or lintel of a window-frame, where,as is quite the fashion, the lower sash is made longer thanthe upper andruns up into a box. When the sash is drawn down again, the open niouthof the box, which would otherwise be unsightly, is occupied by thesash-follower.

The objects of my invention are to provide Y a sash-follower which shallbe automatic or self-acting, noiseless in its workings, exactly fittingthe opening, and. capable of ornamenta tion. These results I attain 'bythe niechair ism illustrated in the following diagrams, in.

`horizontal section or plan of the box, looking down at thesash-follower as it lies when closing the box. Fig. 4 is a verticalsection ofthe window-frame, box, and follower from a side view. Fig. 5is a vertical section (enlarged) of box and follower, showing thefollower raised by the sash entering` the box. Fig. 6 is Va verticalsection (enlarged) of box and follower, showing the follower closing thebox. Fig. 7 is a perspective view of portion of follower, showing therelation of the strikingpiece B to the follower.

The sash-follower consists of a lid or slab, A, preferably made of suchform and material as to match the window-frame on its lower or exposedside, fltting the mouth of the box,

sash plays, and cut away a little at the hinged `l slightly overlappingthe space in which .the 5o end, so as not to impinge, when lifted, onthe frame. (SeeFig. 5.) IThislid Orslabishinged within the box, at theend lying over the upper sash, upon loose or free jointed hinges D D,fastened to its back and to the side of the box in such a manner as 'tooccupy, when closed, space enough to prevent the lid from being balancedor on its center when raised up by the sash. At each end of the lid areconvex striking-pieces -B B, of wood, rubber, or other suitablematerial, which, running below the lid when it lies horizontal, see Fig.6,) encounter the sash iirst when it is lifted, causing the follower tobe raised evenly and smoothly, and avoiding abrasion of its undersurface. At the back of the lid A is another projection orstopping-piece, C, intended to supplement the hinge D in preventing thelid from being raised so near the perpendicular as to balance throughany rnstiness or defect of the hinge. This is not a necessary partiofthe invention, as the whole piece is hinged off' its center, butvpromotes certainty, and is convenient. The thickness of the pieces A,B, and C should be so graduated as just to fill the space between thesash, when lifted into the box, and the side ofthe box. (See Fig. 5.)

The original position of the follower is as shown in Figs. 3, 4, and 6;The sash on beingraised strikes the convex pieces B B and lifts thefollower out of sight into the position shown in Fig. 5. As soon as itpasses by the pieces B B on being lowered the`whole follower at oncedescends by its own weight into its former position, `and forms,apparently, a continuons part of the window-frame.` s

Having thus described my invention, I claim as new and desire to secureby Letters Patent- In a window-frame, the swinging lid hinged ott' itscenter and provided with the projecting striking-piece, in combinationwith asliding sash, for the purpose and in the manner above described. Y
